METHOD AND APPARATUS FOR TAKING A PROOF FROM TYPE-CAST SLUGS Filed Dec. 50, 1959 2 Sheets-Sheet 2 United States Patent O 3,143,293 ME'IHD AND VAIPFAIA'IUS FR TAKING A PROF FROM TYPE-CAST SLUGS Richard G. Sterling, 18 Elvira Drive, Belleville, Ill. Filed Dec. 3i), 1959, Ser. No. 862,880 I7 Claims. (Cl. 199-61) The present invention relates to a proof maker for a type-casting machine. Broadly the purpose of the inven- Ytion is to provide a method and an apparatus for autopaper over a press element that is disposed opposite the exposed, lettered edge of each slug as it is delivered from the chute to the galley. The movement of the rst elevator of the type-casting machine is a preferred source -of movement to cause the paper and the typed edge of the slug to be brought together to produce an imprint from the slug on the paper, after which the paper and the slug are again separated, the paper is advanced by a step, and (upon introduction of another slug into the galley) the joggr moves the thus imprinted slug into its iinal place in the galley.

Broadly, it is an object to provide a proof-making apparatus for a type-casting machine, that makes a proof of each slug as it is manufactured.

It is a further object of the invention to provide such a proof maker that will supply a proof for each slug, which proof is completed simultaneously with completion of the slug and its delivery to the galley. In particular, it is an object of the invention to provide a proof maker that takes a proof from each type-casting slug and completes the same by the time the slug is iinally jogged into place in its galley.

It is another object of the invention to provide a method for obtaining proof from type slugs during the process of making them; and especially a method that will obtain a print of each slug on paper during the process of making and assembling slugs in a galley. Speciiically it is an object to provide a method of interposing the making of a proof into the usual procedure of manufacturing type slugs.

Further objects include the provision of apparatus that is exible, adjustable, and conveniently constructed for use in different type-casting machines.

More particularly, it is an object of the invention to provide such an apparatus that is caused to move through its full cycle by means of the movement of parts already present on a type-casting machine, and particularly to receive its principal movement from the normal movements of the first elevator of the type-casting machine.

Other objects of the invention will appear from the description and claims to follow.

The present invention is an accessory for a type-casting machine, such, for example, as those illustrated in Intertype Book of Instruction, copyrighted in 1943 by Intertype Corporation. Generally speaking, machines of this kind feed letter matrices and wedges to a mold wheel where, duly clamped, they can cooperate with the wheel to form a mold to receive the molten lead to form the type castings or slugs. After each casting is made, the mold wheel, which usually has its axis horizontal, is rotated, and the slug is ejected from it by an appropriate ejector blade. The slug descends through a chute and is deiiected to a galley, which may be an inside or an outside galley, according to the design of the machine. A jogger arm then moves the slug into appropriate alignment in the galley with previously-made slugs, each representing a line of the copy.

Heretofore, it has been necessary to compose a complete galley, lock it up, and set it in a printing press in order to make a proof. rIlle present method and machine make a proof from each slug as it is delivered from the mold wheel to the galley and jogged into place there.

In the drawings here illustrated, the first elevator slide Ztl of the type-casting machine is mounted for vertical movement in the guide frames 21. These guides 21 are part of the supporting structure of the machine and therefore represent a base from which the elevator operation, as well as other parts of the machine, can be supported. It will be understood that in each normal casting operation by the machine, the elevator 20 is automatically moved from a middle position of rest, downwardly, then upwardly to above the starting position, and finally back to the starting position.

A gallery 23 to receive the slugs is also supported on the base 21 by means 24 here shown only diagrammatically. Ihere is a slug chute 25 that receives slugs ejected from the casting wheel and directs them to what is the right end of the galley 23 as viewed by the operator of the machine. The slugs come to rest against the edge V26 of the galley. Ultimately they may be forced against the spring-held, slidable angle plate 27, in the known manner. The machine also includes a slug lever or 3 jogger diagrammatically illustrated at 28 designed to push the slugs, delivered by the chute 25 to the galley 23, leftwardly against the angle plate.

The foregoing parts are entirely conventional and do not of themselves form any part of the present invention. Also, FIGURES 14 and l5 diagrammatically illustrate the mold wheel at 30. The casting is normally done at the twelve oclock position, following which the wheel makes three quarters of a revolution during which the slug is sheared in conventional fashion. Ultimately it arrives at a three oclock position, from which it is ejected into the chute 25. Conventionally the mold wheel 30 is located behind the elevator 26. Since this is well-known, it is not illustrated any further.

The apparatus of the invention includes a supporting frame, generally indicated at 33, mounted on the base of the machine. This supporting frame may embody a bracket 35 secured appropriately to the vise frarne or other part of the machine base. There is a Vertical bar 36 on the bracket 35, and to it is fastened a horizontal bar 37 going across the forward and lower edge of the galley 23. This support frame also has a vertical column 38 to which an upper horizontal stretcher or strut 39 is attached. The other end of the stretcher 39 comprises a telescopic extension portion 4t) that isadjustably fixed to the main element by a set screw 41. The extension 4t) is secured to the frame of the machine as indicated at 42. This arrangement is designed to give rigidity to the vertical column or post 3S. This arrangement provides for tting the apparatus on different machines where the spacing from the vertical post 38 to the machine frame may not be uniform. j

The frame 33 is adapted to support a roll of paper and to provide for its being fed in a stepped manner across the top of the slugs successively introduced into the galley. To this end the frame supports a vertically movable slide 47. The slide 47 is guided in guides formed in the stretcher 39 and in a bracket 48 projecting rearwardly from the vertical support 38 below and parallel to the stretcher 39. Appropriate slide bearing plates Si) and 51 are attached onto the stretcher 39 and the bracket 48, respectively, by screws and can be removed to enable the slide 47 to be installed. It will be observed that the bracket 4S is adjustably mounted on the vertical post or support 38 by a screw 54 that fits through a slot 55 (FIG. 4) in the vertical support 38.

There is a paper roll supporting bracket 60 that has a vbackwardly and upwardly projecting end 61 upon which can be slipped the paper roller 62 by means of which the paper roll can be held. The bracket 60 has a flange 63 against which the paper roll rests. The roll-supporting bracket 60 is anged at 65 (FIG. 6) and has its threaded end passed through an appropriate hole in the slide 47. A nut 66 on the other end of the bracket 60 is adapted to hold the bracket in place, the arrangement permitting an angular adjustment of the bracket about the attachment aforesaid to the slide 47. The angular adjustment is designed to enable the paper roll to be made parallel to the galley.

Also held to the shank of the bracket 60 by the nut 66 is a paper feeder housing 70. As shown in FIGURE 10, this housing has a bracket 71 attached to the Side of the housing by bolts. This bracket has an olf-set 72 with a hole 73 (FIG. 10) that receives the shank of the paper roll-supporting bracket 60, so that the supporting bracket 71 is also held to the slide 47 by the nut 66 and the bracket 60.

The housing 70 itself comprises a member having a bottom wall 75, two end walls 76 and 77, and one side wall 78. An angular cover member 79 has narrow end anges 8G and 81 as well as a side ange 82 and a top flange 83. A rod 84 swivels the cover 79 to the ends 76 and 77 of the main housing so that the cover may be swung out to open the top of the housing 70.

The main housing portion 70 supports two paper feed rolls. They comprise an idler roll 88 that is preferably covered withsome rubber material. It is mounted in appropriate bearings in the 'end walls 76 and 77 of the housing for free rotation therein. Adjacent it and a little below it within the housing is a feeder roll 90 similarly covered with rubber, and similarly supported in brackets and bearings in the end wall 76 and 77 of the housing 70. There is a slot 92 in the bottom wall of the lhousing to permit the paper to be fed upwardly thence between the rollers 8S and 90A and finally out an additional slot 93 provided between the wall 78 of the housing and the righthand end of the cover 7i).

The feed roller 96 has a shaft 96 that extends upwardly beyond the end wall 77 of the housing. On its outer end it has a gear 97 having a hub 9S that is latched onto the shaft by a reversible ratchet 99. By this arrangement the hub 9S can be tted over the shaft 96 in a driving relationship thereto, but in a manner to permit relative rotation between the two in either direction as selected by the ratchet 99.

As noted, the paper roll bracket nut 66 is releasable to enable both the paper roll and a feeder roll to be adjusted into parallelism with the galley.

In addition to the paper roll and the feeder mechanism, the slide supports a press foot 103 at its bottom. This press foot may be a casting with spaced ears 104 through which a swivel pin 165 passes to secure them adjustably to the bottom end of the slide 47. It has a pad 106 on its under surface to cushion the printing operation to be described. The foot 163 also has another ear 108 `at its upper end, this being designed to receive the bent end 199 of a hook 110. The other end of this hook is threaded into a sleeve 111 having a hole 102 to receive a screw 113 passing into the slide 47. By adjusting the effective length of the hook through the turning of the sleeve 111 onto the threaded end of the hook, the angular relationship of the head 193 can be adjusted into parallelism with the galley and can be secured into such adjusted position.

A spring 115 has one end attached to a pin 116 projecting from the slide 47. This spring 115 yields upon downward movement of the slide, and returns the slide upwardly.

FIGURE 16 shows a paper roll 117 from which the strip of paper 118 is drawn down under the presser foot 1113 so that it overlies the galley. The end of the strip of paper is then passed through the entrance slot 92 of the housing 70, thence between the two rollers 88 and 90, and finally out of the housing through the slot 93.

The driving arrangement for the apparatus causes it to be operated each time the elevator 20 goes through a cycle of operation. It will be remembered that the elevator normally tirst descends, then rises from its lowest position to a position above its starting position and finally returns to its starting position.

The elevator has a bracket or arm 120 secured to its top end and projecting outwardly therefrom. It is shown in plan view in FIGURE 12. Its outer end has a notch 121 for a purpose to be described.

The upper end of the slide 47 has a laterally extending shelf 122 secured to it by a screw 123. There is an upstanding pin 124 mounted on the shelf 122 to lie parallel to the slide 47. A cushioning spring 125 surrounds the pin 124 and is retained thereon. A washer 126 is disposed across the top of the spring and a similar one may be at the bottom.

The pin 124 is located directly below the top of the arm 123 on the elevator slide 20. The axis of the pin 124 coincides with the axis-or" the notch 121 in the arm 120, so that when the elevator descends, the arm 120, as shown in FIGURE 4, may straddle the pin 124, and engage the washer 126 and the spring 125. By this arrangement, the descent of the elevator slide 2.0 causes the slide 47 to be depressed. The spring 125 is of such force that the slide 47 normally descends with the elevator 20. However.

when the elevator is stopped in its downward movement, further movement of the elevator slide 2G compresses the sping 125.

In order to cause the paper to be fed, there is a rack 130 mounted on a bracket so that it 'lies alongside and parallel with the elevator slide 2t) and in position to cause its angular teeth 131 to be engageable with the teeth of -the gear wheel 97 on the roller 96. The gear wheel 97 is engageable with the shaft of the roller through the oneway ratchet drive 99.

Adjacent the face of the mold wheel 3i) there is an ink roll 135 mounted on a suitable bracket 136. The ink roll 135 is located in the manner shown in VFIGURES 14 and l5 so that each slug, after it has been cast at the twelveoclock position in FIGURE 14, is moved across the ink roll as the mold wheel 3i? is rotated. Then each slug that is ejected at the three oclock position descends in the chute 25 with its lettering inked.

The end of the galley 23 adjacent the mouth of the chute 25 has an elevation in its floor, here formed by an elevation plate 144i?, shown particularly in FIGURE 6. This plate extends under the edge of the press foot 103 on the slide 47 and thereby elevates the slug last delivered from the chute slightly above the previously delivered slugs. As is known, the jogger or galley arm 23, in the course of the operation of the type forming machine, forces the slugs across the galley against the angle plate 27. In the machine as illustrated in FIGURE 6, several slugs 143 illustrated in dotted lines, have previously been formed and moved over by the jogger against the angle plate 27, and a slug 144 is in position to be printed.

Operation At the outset, a roll of paper 117 is fitted over the roller 62 against the flange 63. `The cover 79 of the feeder roll housing 7 t) is swung open. The end of the paper is drawn from the roll, under the foot Iii?, on the bottom of the slide 47, and thence up through the slot 92 in the bottom of the slide 47, and between the two rollers 88 and 90. When the cover is swung back into closed position, the end of the paper should project out through the slot 93.

As a preliminary, the parts would have been set up in an adjusted position, as will be explained hereafter.

With the paper thus in place, the normal operation of the type-casting machine causes the elevator slide Zit to move from the position illustrated in FIGURE 1 initially downwardly, at which time the matrices are moved in to position to receive the mold disk to make the lettering on the slugs. As the elevator descends, carrying the matrices and space bands between the vice jaws of the machine (not shown), the mold disk turns a quarter revolution, to casting position. Details of this operation are unnecessary here. In this action, rst the rack 13@ engages the gear 97 to cause the roller 90 to be turned in a direction to feed the paper strip forward the distance of one line of type. Thereafter the arm 12d engages around the pin 124 and, acting through the spring 125, causes the slide 47 to descend. At the start, however, thereis no slug in the galle so no proof is taken.

In the meanwhile, when the elevator is down, a slug is being cast md molded in the mold disk 3i). Following the molding, the mold disk 30 is retracted from the matrices in the vice, and the elevator is raised to the transfer position. During this time the mold disk 3G is rotated three-quarters of a revolution to the slug-ejecting position. During this rotation of the disk, the type-edge of the slug passes by the ink roll 13S and becomes inked. Thereupon the ejector operates to discharge the slug into the chute. The elevator 29, is, of course, finally returned to its starting position.

The slug thus formed falls into the chute with its type edge forward. The chute causes it to be delivered onto the elevation plate 149 of the galley with its type edge upward. It slides to the position in the galley indicated in dotted lines in FIGURE 5. The joggerarm 28 then acts to press the-slug to the right in FIGURE 6. If it is the initial slug in the galley, it is pressed against the angle plate 27. Otherwise it is pushed against the previous slug in the galley and pushes that slug beyond the edge of the elevation plate 140. This then disposes the new slug under the pad 1% on the foot 193 with its type edge elevated above that of the previously made slugs. If there are other slugs in the galley on the plate`14t), made .later than the slug 144, they will not be printed because the pad 1% is too narrow to cause the paper to engage the top edge of any except the slug 144.

Thereupon the cycle is repeated to make a new slug. In this subsequent descentof the elevator 20, the paper feed roller is again operated to advance the paper, after which the slide 47 is lowered to cause the foot 193 to press the paper against the inked, upturned, typed edge of the slug, making a proof therefrom. When the elevator 2t) again is lifted away from the slide 47, the spring lifts the slide and the paper away from the slug, so that the galley is free lto receive a subsequent slug.

Normally the final downward movement of the elevator slide 2t? will cause some compression of the spring 115. This aids in making an imprint and also it eliminates the necessity of exact positioning of the parts. In the return movement of the elevator slide 20 the ratchet 99 enables the rack 136 to act upon the gear 97 without operating the roller.

Thus, by this arrangement, in the very act of making slugs and accumulating them in the galley, the operator makes a proof that is immediately accessible. At any time he may draw the strip through the rollers and tear oif any part of it against the edge of the slot 93.

This arrangement enables the printer to obtain his galleys and make any corrections almost immediately. He is not required to remove the galley from type-casting machine and set it'up in a press in order to make a proof. He is not even required to wait until a predetermined number of slugs are completed before he can make proof.

In the construction and assembly of the machine for making proof, the threaded hook 116 permits an adjustment of the angularity of the foot 103 on the slide so that it can be accurately positioned with respect to the slugs in the galley. If the apparatus is transferred to a different machine, the telescopic construction of the stretcher 39 enables appropriate adjustment to be made to accommodate variations in the dimensions of the new machine over any former one. In like manner the bracket 4S may be moved vertically and set in xed position which may be necessary, forexample, when the slope of the galley is changed. As previously stated, the angularity of the paper roll and the feed rollers can be readily adjusted by loosening the nut 66.

It is evident that modications can be made of this equipment and still preserve one or more of its desirable features. For example, the ink roller can be located near the chute or outlet to the chute rather than in connection with the mold wheel 30. If a printing paper, carbon, or ribbon be used, the ink roll may be omitted. The paper feed mechanism can be varied, although the one `illustrated has particular advantages that have been indicated.

It should be remembered that one aspect of this invention consists in the method of producing inking of a slug in the process of its manufacture and the taking of an impression therefrom `prior to the time it is finally disposed in the galley but during the normal process of delivering it to its nal .position in the galley.
